Product Description
Mounting in 24kV Switchgears Porcelain Disconnectior Switch
1 The product, suitable for service in a 12kV 50Hz AC 3-phase power system, is a main part of a metal enclosed switchgear. The main contacting knife is used for circuit opening or closing without load, when maintenance of electric equipments during power out, the earthing knife makes a man-made earthing while its closing to guarantee a reliable "ground potential” protection for maintenance personal for safety requirement. It is one of main measures to avoid from electric shock to personal.
2 Features of Main Structure
2.1 On the basis of type GN19 isolating switch, an earthing switch is added to form a new isolating switch GN24-12Q. Every phase conductive part is fixed on a bottom frame by two post insulators. Type GN24-12CQ/630, 1000 or 1250 isolating switch is wall gone-thru type, C means a post insulator is on one side, the other side is a bushing. GN24-12SCQ/630, 1000 or 1250 is double earthing and wall gone-thru type. Three phases of the switch are mounted in parallel. The conductive part per phase consists of a contacting knife, a stationary contact and an earthing knife. There is a pull rod insulator connected at the mid of every contact knife. The pull rod insulator is connected to a main shaft mounted on the bottom frame. Two main shafts for earthing knife and contacting knife are connected respectively by a driven crank arm, and the crank arm is connected to the operating mechanism type CS18-I, CS18-II, CS18-IV or CS18-VI.
2.2 At contacting points for GN24-12CQ/1000(1250) isolating switch (except the bolt fixing contacting of the earthing knife), there is a magnetic locking plate, its role is to strengthen the attract force between two main knives and two earthing knives, enhance the contacting pressure at contacting places, so to heighten the dynamic and thermal stability of the isolating switch while short circuit trouble happens.
